Healthbook app may monitor heart rate, hydration, blood sugar, more

Apple’s upcoming Healthbook app may track users’ heart rate, hydration, blood pressure, blood sugar, sleep, and more, according to a new in-depth look from 9to5Mac. The article offers “complete recreations of screenshots” which appear to answer numerous questions as to what Apple is testing in health and fitness tracking. Bloodwork, oxygen saturation, and blood sugar sections of the app will monitor a user’s blood. Apple could also track hydration and respiratory rate using Healthbook, as well as sleep cycles.

As one might expect, Healthbook will also be used in fitness tracking, to examine weight, activity, and nutrition. An Emergency Card section would store vital health information that can be used be a doctor or emergency technician in times of health crisis. It’s unknown how Healthbook will acquire the data, though the iPhone, iWatch, and third-party apps or devices could all contribute information. Healthbook could be released with iOS 8, but the report notes—likely for cautionary purposes only—that the app “could be pushed back to a future operating system version or cancelled entirely.”
